Please understand that everyone here sympathizes with you.
It isn't that nobody cares.
When your Husband decided that he no longer wanted to be Married and chose to Divorce you instead of working on the issues together was terribly selfish and heartbreaking to your family.
With that in mind, please also understand a common misconception.
He is not your property. He doesn't belong to you. He is able to make his own choices for his own life whether you approve or not. You are not his Mommy. He owes you absolutely no explanations for his choices. He doesn't ask you for your opinion so please don't share one with him. In regards to your Son, leave him out of it.
There is a common saying that reminds me of you, "Hell hath no fury like a Woman scorned" The more you snoop and stalk, the angrier you will get at the information you will find.
This is what scares me about your situation.
There can be no testimony without a test. I am praying to go through this test and come out the other end with a new and better marriage then before.
